IDT™ / ICS™ SPREAD SPECTRUM CLOCK GENERATOR
MK1493-14
SPREAD SPECTRUM CLOCK GENERATOR
Controller (host) sends a start bit
Controller (host) sends the write address D2
ICS clock will acknowledge
Controller (host) sends the beginning byte location =N
ICS clock will acknowledge
Controller (host) sends the data byte count = X
ICS clock will acknowledge
Controller (host) starts sending Byte N through Byte N + X - 1
(see Note 2)
ICS clock will acknowledge each byte one at a time
Controller (host) sends a Stop bit
